Article Description

In this letter, the authors report the photoluminescence studies of Eu doped YO nanorods, which have been synthesized by rapid microwave hydrothermal route within 6 min. The nanostructured Eu doped YO is characterized by x-ray diffraction, transmission electron microscopy, and photoluminescence. The emission spectrum shows transitions from the excited 5D state to F (7=0,1,2,3,4) levels of the Eu ion. The most intense peak around 612 nm is due to the D →F transition, expected from the Judd-Ofelt selection rules [B. R. Judd, Phys. Rev. 127, 750 (1962); G. S. Ofelt, J. Chem. Phys. 37, 511 (1962)]. Photoluminescence measurements demonstrated that the nanocrystalline Eu:YO phase shows higher photoluminescence intensity. © 2006 American Institute of Physics.
